SPECIFICATION forming part of Letters Patent No. 588,201,1:lated August17, 1897.

Application filed March 1897.

To @ZZ whom it may concern/3 o Be it known that I, ALoIsE WAECHTER, asubject of the Emperor of Germany, residing at Strasburg, Alsatia, intheEmpire of Germany, have invented new and useful lmprovements in Sweep orShaping Saw-Machines, of which the following is a specification.

This invention relates to an improved construction of sweep or shapingsaw-machine with rotatable saw-blade, which I will de- Ascribe withreference to the accompanying drawings'. y

Figure l is a detail view of the pulley and clutch mechanism for drivingthe lower crank-V shaft. Fig. 2 is a similar view showing the connectionwith the lower spindle. Fig. 3 is a detail View of the upper spindle.Fig. 4 is a section on line F C of Fig. 8. Fig. 5 is a detail of thedrill-spindle. Fig. 6 is a front elevation, partly in section, of theupper spindle and the means for raising it. Fig. 'vis a side view of thesame. Fig. l8 is a detail of the drill-rod connection. Figs. 9 and 10are respectively front and side elevations of the complete device.

To an arc-shaped yoke y, Figs. (i, 7, and 9, are attached two spiralsprings y', tending to draw the saw upward, the hook-shaped ends ofwhich springs are connected by links y to the head s of the spindle j.The tube r, held in a clamping-bearing t, is attached to the yoke y by abracket x and embraces the spindle j, and can be vertically adjusted inposition to suit the thickness of the wood to be worked by loosening thewing-nuts t of the clamping-bearing Z. The spindle j is guided in thetube r at top in the bush Z' and at bottom in the bearing Z, Fig. 3, andit is connected by a screw-thread and nut n with a clamp n for holdingthe saw-blade.

A caoutchouc ring fitted over n serves to lessen the force of any impactof the lower end of the spindle against the bearing Z.

The key p in the bearing Z corresponds with a vertical groove in thespindle j. The bearing Z has a circular groove o, into which takesetting-screws o on the tube r.

The spindle j consists of two separate parts that are connected togetherby means of a ball-andsocket joint s. In consequence of Serial No.629,243. (No model.)

this the saw-blade can be turned in all directions by means 'of asocket-like handle m, because the bottom pivot of the lower spindle g,to which the lower end of the saw-blade is attached and which slides inbearings h h in the tubular guide t', is also movable in a universaljoint f. The spindle g is provided with a clamp like the spindle j andhas a caoutchouc ring for weakening any impact with the guide. Theuniversal joint f is attached to the connecting-rod e of the crankshaftc, which is driven by a cord-pulley.

The drilling device employed in combination with the saw is arranged asfollows: The

clamps @c and on on the tube r serve to hold a drill-rod u, with handleu and pin e secured by a setting-screw 2f, Figs. 6, 7, 8, and l0. Inplace of theclamp fn, the drill-head q, with nut q', Fig. 5, is screwedonto the spindle j, and a rotary motion is imparted to the latter bymeans of a cord leading from the before-mentioned cord-pulley round awhirl onthe handle m, and the downward motion of the drill and spindleis controlled by handpressure upon the handle u' of rod u.

For throwing the drilling device out of gear the setting-screw z isloosened, pin n is drawn out of the hole in spindlej, and is then fixedagain by the screw z.

The above-described machine possesses the lessential advantage that longpieces of wood drilling device enables the necessary holes to be drilledfor cutting through,as also such cutting itself, to be eifected in thesame machine that serves for the sawing, which enables a great savingottime tobe effected in the case of large pieces of wood and smallworkshops,

Having now particularly described and as- IOO certained the nature ofthis invention and in pin passing through the depressing-rod and whatmanner the same is to be performed, I engaging the upper portion of thespindle, declare that what I claim issubstantially as described.

In combination the tube fr, the two-part In testimony whereof I havesigned my 5 spindle adapted to have vertical and rotary name to thisspecification in the presence of I5 movement therein, the lower portionof said two subscribing witnesses.
